2.4.5 RS-232 Serial Communications
The CN10 connector is intended to provide a connection point for the RS-232 serial communications. One RS-232 port is
available. See
for the pin assignments for the CN10 connector.
2.4.6 Power
The 380 Synergy Indicator is powered by 4 C-Cell Batteries or an optional 12 V adapter (PN 206433). When the adapter is
inserted into the power jack, indicator power is disconnected from the battery holders and batteries no longer drain. Power
adapter does not charge the batteries.
Optional power adapter (PN 206433) is the only external power source allowed to be used.
Ensure that battery covers are screwed finger tight. If covers are not fully screwed on, the indicator will not function.
